I always thought it silly that this is the case. But what do I know. Concidering that the V-Hanger is nearly the only resource to sustain that base besides the measly maned ack gun, one would think that it'd take more than one egg to drop it. Im not sure because I haven't looked at the charts lately, but I think it is 1200lbs needed to drop a V-Hanger at a V-Base. Could be wrong.
Either way, it seems as though it should be harder than it is.
